For new readers and those who request to be “好友 good friends” please read my 公告欄 firstOn Metaheuristics for Stochastic Combinatorial Optimization ProblemsThis blogger has spent his entire professional live in the subject of OPTIMIZATION. Generally speaking錛 there are two major types of such problems. First type may be classified as those involving continuous variables where calculus and other related analytical techniques play a major role. Stochastic optimal control theory being the most complex branch and representative of this type of problems. The other type of optimization problems is the subject of the title of this blog. Problems of this type are basically combinatorial. Since very little is continuous in such problem錛 solution methods generally involving “search” among a very large set of distinct possible candidates. While this blogger is generally familiar with the methodology in this combinatorial optimization area錛 he has not personal worked on problems in this area and contributed to the literature. Thus錛 it is a pleasure to report that I recently came across a very good and thorough literature survey/review of this area in a 2008 paper with the title of this blog (A_survey_on_metaheuristics_for_stochasti.pdf ). It is rather long but can be read in small doses as coverage of each subtopics is not that dependent on other sections. I highly recommend this paper.呂乃基疫情開始至今已近三個多月,中國採取果斷措施到現在也已有兩個月了。本想寫點什麼,一時又不知從何落筆。心情五味雜陳。眼下,疫情進入“下半場”,由此提供了一個全球的視野。走向世界的疫情如同一面鏡子,照出林林總總之人性,照出各國之間的文化差異。于是又燃起動筆的念頭。總題目為“疫情雜議”,副標題暫為“疫情中的人性與文化差異”。先說說這兩天成為輿情中心的“群體免疫”,
